You asked:

Evaluate the expression: \(1.5 \cdot 5.4\)

MathBot Answer:

\[1.5 \cdot 5.4 = \frac{81}{10} = 8.1\]

\[\begin{aligned}1.5 \cdot 5.4& = \left(1 + \frac{5}{10}\right) \cdot \left(5 + \frac{4}{10}\right)\\& = \left(1 + \frac{1}{2}\right) \cdot \left(5 + \frac{4}{10}\right)\\& = \frac{3}{2} \cdot \left(5 + \frac{4}{10}\right)\\& = \frac{3}{2} \cdot \left(5 + \frac{2}{5}\right)\\& = \frac{3}{2} \cdot \frac{27}{5}\\& = \frac{81}{10}\end{aligned}\]
